This invention relates to a safety razor, and more particularly to asafety razor having a novel type of razor blade support.

The object of the invention is to provide a safety razor which isconstructed so that the user can tell which side of the blade has beenpreviously used, there being windows for enabling a person to observeadvertising matter that may be arranged on the razor blade.

Another object of the invention is to provide a safety razor whichincludes a handle, a base, and a clamping plate detachably connected tothe handle and base, the razor blade adapted to be positioned betweenthe base and clamping plate, there being longitudinally extendingshoulders or ridges arranged on the base for providing the properflexing for the blade.

A further object of the invention is to provide a safety razor which isextremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this application, and inwhich like numerals are used to designate like parts throughout thesame:

Figure l is an end elevational View of the safety razor, constructedaccording to the present invention;

Figure 2 is a front elevational view of the safety razor constructedaccording to the present invention;

Figure 3 is a side elevational view, with parts broken away and insection;

Figure 4 is a top plan view of the safety razor in assembled position;

Figure 5 is a top plan view of the base;

Figure 6 is a plan view of the clamping plate.

Referring in detail to the drawings, there is shown a safety razor whichincludes a cylindrical handle Iii that may be fabricated of any suitablematerial, and the handle It may be hollow, as at H, so as to reduce theweight thereof. The exterior surface of the handle I may be knurled, asat 2, so as to facilitate the gripping thereof, and extending throughthe handle I 0 is a bore 53, Figure 3. The inner portion of the bore I3is threaded, as at I l.

Arranged transversely with respect to the end of the handle I0 is a baseI5. The base I is provided with an opening I6 which registers with thebore I3. The base l5 includes a central I raised portion [1, andarranged on each side of 2 edged razor blade I9 is arranged contiguousto the base l5, and the pointed shoulders l8 insure that the blade Itwill be properly flexed.

Extending through the bore I3 is a cylindrical stem 28. The stem 29includes a threaded end 2! which engages the threaded portion M of thebore l3, and the other end of the stem is threaded exteriorly, as at 22.The threaded end 22 is arranged in threaded engagement with aninteriorly threaded sleeve 23 which is formed integrally with or securedto the clamping plate 2G.

The clamping plate 24 is provided with a pair of spaced parallel slots25 which define windows whereby a person will be able to readily observeadvertising matter that may be arranged on the razor blade I9.

The clamping plate 24 is further provided with a pair of spaced, curvedribs 26 and 21. It will be seen that the ribs 26 and 21 are of differentsize, and since these ribs 26 and 21 are of diiierent' sizes, the userof the razor blade will be able to determine which cutting edge of therazor blade 19 has previously been used. Thus, if the user used thecutting edge of the razor blade which was adjacent to the large rib 2?,then on the next shave the user would remember to use the oppositecutting edge which is adjacent to the other rib 26.

From the foregoing it is apparent that a safety razor has been providedwherein a person will be able to observe advertising matter which may bearranged on the razor blade I9. Thus, the user can look through thewindows 25 and observe any advertising matter on the razor blade I9.Also, the provision of the rolled ribs 26 and 21 enable the user toascertain which side of the razor blade has already been used.

Further, it will be seen that one cutting edge of the razor blade i9projects further beyond the clamping plate 24 than the other cuttingedge, so that the user will be able to use one side of the razor forobtaining a close shave, while he will be able to use the other side forobtaining a smooth shave. Also, the curvature in the ribs 26 and 2'!permits the skin to be pushed onto the cutting edge of the razor bladeso that a smoother and more efficient shave will be provided. Also, theslots 25 provide flexibility to the clamping plate, so that a smoothershave will be accomplished. Further, the clamping platez i may be madeof spring steel, so as to give it greater flexibility.

What is claimed is:

1. In a safety razor, a handle, a base arranged adjacent said handle,there being a longitudinally extending bore arranged in said handle,said base being provided with an opening for registering with the borein said handle, a cylindrical stem projecting into said bore anddetachably ccn eoted to said handle, and a guard plate having a sleevedetachably connected to the other end of said stem, said plate and baseadapted to hold therebetween a razor blade, there being windows arrangedin said plate for observing the razor blade, and spaced, parallelpointed shoulders projecting from said base for supporting the razorblade, said clamping plate being provided with curved ribs of differentsizes, the free edges of said ribs being positioned inwardly of saidshoulders. said sleeve maintaining the central portion of said platespaced away from said base.

2. In a safety razor, a handle provided with a longitudinally extendingbore, a portion of said bore being interiorly threaded, a base arrangedadjacent one end of said handle and provided with an opening forregistering with said bore, a cylindrical stern having its opposite endsthreaded and projecting into said bore and engaging the threaded portiontherein, the central portion of said base being raised, a pair ofspaced, parallel pointed shoulders extending from said base, a clampingplate provided with a threaded sleeve engaging the outer end of saidstem, said 4 plate and base adapted to clamp therebetween a razor blade,there being a pair of slots in said plate defining windows, the oppositeedges of said plate being shaped to provide rolled ribs of dif- 5 ferentsizes, the free edges of said ribs being positioned inwardly of saidshoulders, said sleeve maintaining the central portion of said platespaced away from said base.
